- 3 Application fled June 1,

To all whom it may concern:

Be it known that I, PEDRO NAVARRO, a citizen of Argentine Republic, residin at New Iberia, in the parish of Iberia and tate of Louisiana, have invented certain new and useful Improvements in Cell-Case Partitions, of which the following is a specification.

My invention relates to cell cases, such as are used, for example, for packing egfgs An object of my invention is to rovide or rapid and accurate formation of t e separate partitions and their rapid assembly, by aid of suitable machinery, while insur'in 'that the partitions will be securely locke upon assembly. Other objects will appear in the course of the ensuing description.

I attain these objects by the device illustrated, for example, in the accompanying drawing, in which Figure 1 is a perspective view of parts of two partitions made according to my invention and assembled;

Fig. 2 is a partial side elevation of one of the partitions; and p Fig. 3 is a partial longitudinal vertical section on the plane of the line 3-3 of Fig. 1, with an additional partition.

It will be understood that the cell case made of my improved partitions is similar to many others well known in the art, in that it consists of a number of flat strips of pasteboard or the like, forming the partitions, crossing each other at intervals so that between each four adjacent strips a rectangular cell is formed to receive an egg or other object to be held and protected by the structure. Therefore, only parts of two such partitions are illustrated, in Fig. 1, and only three ir Fig. 3.

The two partitions 1 and 2 are identical, each being cut away to receive an uncut part of the other when the two are inversely assembledas shown in Figs. 1 and 3. One of these partitions is shown partly in Fig. 2; the complete artition having any suitable length and belng provided with cuttings to receive any desired number of similar partitions inversely thereto thereacross, which in turn similarly receive. any desired number of similar partitions parallel with the one first mentioned. A usual design, for egg cases, has seven of the partitions each way, forming thirty-six cells. For machine assemblage of these partitions, as is known in 1928. Serial No. 642,802.

the art, it is desirable to bring them together 7 at right angles as shown in Fig. 1 and as they are in use; although one of the requirements is that an assemblage of the partitions,

making a com lete case or filler, can be folded "until all t e partitions are substantially parallel, forming a fiat compact unit readily stored and shipped, to be unfolded for use in packing the articles.

edge l substantially halfway across the parti.

tion, and an eye 5 near the opposite edge 6,

leaving uncut portions 7 and 8 respectivelynext to the edge 6 and in between the eye 5 and the inner end of the slot 3, which portions are adapted to be received in the slot 3 of an inversely assembled partition 2 as shown in Figs. 1 and 3. r

' Slightly less than half-wayinwardly of the length of the slot 3 a lug 9 extends from one side of the slot, having a detention end 10 inward toward the middle of the partition, a deflecting end 11 in the opposite direction, inclining toward the side of the slot outward, and a bearing edge 12 between these two ends 10 and 11 parallel with the general direction of the slot 3 and facing,

over toward the opposite side of the slot,:

which is widened around this lug 9'to the extent that this opposite side runs substantially parallel with the inclined end 11. and edge 12 opposite these respective parts of the lug 9. Inwardly past the lug, this side inclines over toward the other or first men- I gradually'reducing width, and the terminal; part 14 of. uniform width; which uniiorm width is about equal to the thickness of th partitions.

portion 15 of the slot with its sides atella to the general direction and spaced iliketth inner terminal walls of'the,part,.1 1!,aa. equal to the thickness of Q1; 9.5 Outwardly past the lug 9 there is a shqlftuy,

the partitiongand-i outward from this part the walls diyerge, forming an entrance 16 adapted readily to admit the partition in course of assembly with this partition.

The eye 5 is six-sided; its greatest width being at its end 17 toward the slot 3, which end is arallel with the length of the partition. rom this end short sides 18 at right angles to the end 17 extend to converging sides 19 which meet the remote end 20 out toward the edge 6, leaving this remote end 20. of a length about equal to the thickness of the artitions. This eye 5 is I a-lined, across t e artition, with. the slot 3 and so located t lat it will receive the lug 9 oi this region.

outer part of the inclined deflecting end 11 of this lug confined against the remoteend .20 of the eye between. the converged sides 19, and the detention end 10 of thelug, which is. substantially parallel with the length of thepartition, against the similarly disposed wide end 17 of the eye, locking the partitions against transverse separation while at right angles to each other by the engagement of the lug end 10 and eye end 17,- while the close confinement of the opposite end 11 of the lug between the converged sides 19 of the eye, against the eye end 20 secures the partition having the lug in this eye against sidewise displacemenbin In t e opposite region, this inversely assembled partition is secured against sidewis'e displacement by its portion 7 between the parallel sides of the outer portion 15 of the slot 3; and the inner portion 8 is similarly secured between the parallel sides s; the slot portion 14. Being identical in iofihh pe, the two partitions thus hold each other, so that their connection is relatively of each rigid throughout their widths. That part partition opposite its lug 9 is not held against sidewise movement at this connection, but depends for such support upon the lug 9 between the sides 19 of the eye 5 3 at the next connection, as the one at the right in Fig. 3; although the snug fitting between the side of its slot portion 15 and the portion 7 of the crossing partition frictionally contributes to this iolding. The parts are so proportioned that such snug fitting is attained throughout the bearing parts just described, having the slot portions of accurate width to receive the thickness ofthe crossing partitions snugly, and having the eyes 5 and lugs 9 accurately located to engage closely at their ends as before mentioned.

Such accurate fitting of a connection, of course, with' extreme care in assembling, is

not di'flicult even without any special provi-- sion for'faoilitatin it. But for rapid automatic assemblage y means of a machine forcing the crossed partitions together, I

have provided, by the means just described. for securing such accuracy and security of connection with a minimum of distortion of the slot sides and In 9, and for insuring the correct entrance 0% the h1g9 to the eye 5 and the snug seating thereof in the eye. Thus, when two partitions 1 and 2 come together, mutually guided by their entrance parts 16, their lugs 9 are deflected around each other by engagement of their inclined deflecting ends 11, each lug 9 passing around the other in the widened part of the opposite slot 3; then, by engagement of its inclined end 11 with the inner end of this slot 3, again being deflected to one side or the other along the intervening uncut part 8, until reaching the wide adjacent end 17 of the eye 5, which readily admits the lug 9 though deflected to one side or the other, for the lug 9 to advance against one or the other of the converging sides 19 of the eye 5 and be guided to its secure seating against the remote end 20 of the eye.

By providing the short parallel bearing edge 12 on the lug 9. there is sufiicient area of material where the lug becomes forced against the opposite portion 8, to avoid undue distortion of the lug in this passage, so that it practically is intact, witha full extent to its detention end 10 as designed, for effective coaction with the end 17 of the eye, and without any distorted end projections to interfere with the correct entrance to and seating in the eye 5. This-formation of the lug 9 also permits the slot 3, around the lug, to have an easy change of direction, which in turn results in less distortion of the portion 8 of the opposite partition during the passage of the lug 9 thereacross.

The eye 5, having the straight parallel sides 18 between its entrance end 17 and. its converging sides 19, admits the lug 9 with such a parallel bearing ed e 12 for immediate guiding engagement 0 the inclined end 10 of the lug with the one of the conver ing sides 19 of the eye 5 that the lug may ave been deflected toward as before described,

' duced by the-described disposition o. the slot and eye parts, so that the strains on the artitions as a whole, and upon the assembling machine, are minimized, and there is less power required for operation than with par- The obtuseness of all of the titions having more extended projections and less moderate degrees of change in directions of the cuttings.

used, or the kind of articles for which the cases are required, may occur; and therefore, while certain details are deemed preferable, and I have shown and described these rather specifically, I do not wish to be understood as being limited to such precise showing and deserl tion, but having fully described my inventlon, what I claim as new and desire to secure by Letters Patent is:

1. A cell-case partition having a slot from one edge inward, with a lu in the slot having an inner detention end and an outer deflecting end, said partition also having an eye near its opposite edge with a wide end toward the slot and a'narrow end toward said opposite edge, to receive guidingly the lug of another similar partition in said wide end and lock said lug in said narrow end against sidewise movement.

2. A cell-case partition having a slot from one edge inward, with a lug in the slot having an inner detention end and an outer deflecting end and having a bearing edge substantially parallel with the general direction of the slot, said partition also having an eye near its opposite edge to receive 7 the lug of another similar partition.

3. A cell-case partition having a slot from one edge inward, with a lug in the slot having an inner detention end and an outer deflecting end and having a bearing edge substantially parallel with the general direction of the slot, said partition also having an eye near its opposite edge with sides substantially parallel with the general direction of the slot and then converging toward the opposite edge of the partition.

4:. A cell-case partition having a slot from one edge inward, with a lug in the slot having an inner detention end and an outer deflecting end, and having a bearing edge substantiallyparallel to the general direction of the slot, said slot being widened around said lug but having its sides substantially parallel to said general direction near its opposite ends, and said partition also having an eye near its opposite edge I with a wide end toward the slot, parallel sides next to this end, converging sides leading from these sides, and a narrow .end remote from the slot, to which the converging sides lead, the lug and eye being so located that two such partitions, inversely assembled, have the lug of each in the eye of the other.
